Subject [jira] Created: (WAGON-262) Support hashed hostnames in the known_hosts file
Date Wed, 29 Apr 2009 20:37:44 GMT
Support hashed hostnames in the known_hosts file
------------------------------------------------

                 Key: WAGON-262
                 URL: http://jira.codehaus.org/browse/WAGON-262
             Project: Maven Wagon
          Issue Type: Improvement
          Components: wagon-ssh
    Affects Versions: 1.0-beta-5
            Reporter: Wes Wannemacher
            Priority: Minor


This isn't directly a wagon problem, but it was a problem with the older Jsch. Newer versions
of OpenSSH can be told to hash the host names in the known_hosts file... There is some information
on the 'net about the file format, example link - http://nms.csail.mit.edu/projects/ssh/install40-other.php.
Although I have never had a problem before, I ran a bare-metal install of Ubuntu Jaunty earlier
in the week and they have this option turned on by default. Since this was a new machine,
all of the entries in known_hosts were hashed. This means, you try to deploy an artifact using
wagon-ssh and you will get prompted since authenticity can't be verified. There is info on
the Jsch home page that says that later versions (0.4.1?) support hashed known_hosts. I tried
updating the pom.xml file to use a newer Jsch, and all of the unit tests pass. There is also
a nabble thread here (where I converse with myself) about the issue - 
http://n2.nabble.com/release%3Aperform-problem-with-ssh-scp-td2734566.html#none

I'm not going to attach a patch, since all that I have tried to do is update the pom, I haven't
done proper testing.
